Plywood Manufacturing Process: From Log to Finished Product:- The Manufacturing Process of Plywood has a significant impact on the environment, the economy, and society. Plywood is a widely used construction material that is made from thin layers or “plies” of wood veneers that are glued together to form a strong and durable panel and are joined together by Adhesives used for the Plywood Manufacturing Process. A sheet known as plywood is constructed of thin wood layers. Core refers to these thin layers of wood. These cores are bonded together and layered in alternating directions to create plywood. Conforsply is the best Plywood Manufacturer in Yamunanagar that gives the easy plywood manufacturing process for their clients and gives the all important information about how is plywood made?
Plywood is of two kinds: Hardwood and Softwood. In manufacturing plywood, the commonly used hardwoods are those fall in with deciduous species such as larch, maple, oak, cherry, and poplar. These Hardwood plywood are usually used in designing the inner part of houses. On the other hand, softwood falls in with the family of coniferous. Firs and pines are softwoods used in manufacturing process of plywood. By bonding several layers of dry softwood veneers together with a resin, softwood plywood is made.
The Plywood Manufacturing Process: From Log to Finished Product consists of different processes to ensure the quality of the product produced. These methods include selecting the log, debarking, cutting the logs, peeling the log, making a continuous ribbon of wood, cutting and stacking, glueing the wood, pressing the wood, trimming, sanding, and finishing.
Plywood Manufacturing Process: From Log to Finished Product: Step by Step
The plywood is made from trees that are generally smaller in diameter than those used to make lumber. In most cases, they have been planted and grown in areas owned by the plywood company. These areas are carefully managed to maximize tree growth and minimize damage from insects or fire. Let us discuss Step-by-Step Guide for how plywood is made:
Step 1: Sourcing From the Forest
It’s very necessary that all raw logs used in plywood are sourced from legal and sustainable forest concessions. Once trees reach an acceptable level of maturity, they are felled by trained harvesters. Depending on the operation of the mill, vehicles can be used to select and fell trees using satellite imagery.
Step 2: Selection of a Block
Log selection is the second part of the process that involves careful identification and segregation of locks from face back and core veneers in terms of species physical geometry and quality the prime object is to produce veneer from species with accepted physical and aesthetic characteristics.
Step 3: Debarking
Rubber-tired loaders pick up logs from the log decks as needed and then place them on a chain conveyor that transports them to debarking equipment. While the wood is progressively rotated about its long axis, this machine removes the bark using high-pressure water jets or grinding wheels with sharp teeth. The debarked logs are transported into the mill on a chain conveyor and cut into pieces using a massive circular saw that can produce standard-length sheets.
Step 4: Logs Cutting
After being debarked, measure conditioned logs and mark length for cross-cutting to standard size. Cutting logs for manufacturing plywood process requires equipment, skilled workers, and attention to detail that ensures the quality and consistency of the finished product.
Step 5: Peeling of the Logs
The next step is the peeling process. The markings in the log made by the debarking knives during the debarking process are removed using a substantial rotary lathe. The log revolves around the machine against a long blade cutter. The cutting process is like sharpening a pencil except that the blade is parallel with the log at the time of cutting.
Step 6: Transforming into a Continuous Ribbon of wood
In this case, the wood is sized to a standard 4′ x 8′ square. The optimal thickness for plywood is between 1/4″ and 3¼’, however, once the sheets are pressed and glued together, the actual thickness of the finished product is established. As the sheets emerge from the peeler, they are immediately scanned. Following scanning, it is stacked for transfer to drying ovens.
Step 7: Glue Application
The next step is sticking the sheets of veneer together. This is done to determine the desired thickness of the plywood sheets. The commonly used adhesive in manufacturing process of plywood is those synthetic plastics such as phenol-formaldehyde or urea resins. The thin sheets of wood run through the gluing machine. As the sheet pass through, the glue is spread evenly on the back and face of the veneer. The glued veneer is placed on top of the unglued veneer, then followed by glued veneer.
Step 8: Pressing of Wood
After the glued and unglued alternating Plywood Production Process, the sheets which are glued together are pressed using a hot press machine to attain the desired thickness of plywood. An example of this pressing machine is the hydraulic or pneumatic pressing machine wherein pressure, or sometimes heat and pressure are applied to the plies. When heat is applied, the glue hardens quickly and then solidifies as the combined veneer is pressed together. The plywood is considered dry once the pressure is released.
Step 9: Trimming, Sanding and Finishing
The board is hot pressed, stabilized, and allowed to cool before being processed further. The boards are then typically sanded using a large industrial sander after any excess veneer is cut off to ensure the board has square edges. All dents and other faults introduced during handling, such as those brought about by woodworking machines, are removed and this is how Plywood Manufacturing Process: From Log to Finished Product is carried out.
